Connectivity & SD-WAN
SD-WAN is the modern connectivity standard. We build both halves of it.
Every SD-WAN is two networks: the underlay, the physical links a site can get, and the overlay, the software that decides how traffic uses them. Most providers sell one and hope for the other. Optika's founders spent their careers building carrier networks and WANs, so we secure the best possible underlay for each site and configure an overlay that gets the most out of it.
SD-WAN
Underlay and overlay, done by the same people
Deep connectivity, network and WAN experience: from fibre backbones and microwave links to multi-site SD-WAN, the founders have designed, built and operated them at carrier and enterprise scale. That's the team choosing your links and writing your SD-WAN policy.
The best possible underlay
Carrier relationships, site-by-site feasibility and honest advice on what each medium can really deliver. Two independent paths per site as the rule, physical diversity where it exists, and circuits ordered, delivered and escalated by us.
- Fibre, microwave, LTE/5G and satellite assessed per site
- Diverse routes and separate last-mile providers
- Capacity sized from measured traffic, not the brochure
- One contract for every circuit and carrier
An optimum overlay
Fortinet SD-WAN configured for how your business actually works: Microsoft 365, voice, cloud and branch-to-branch traffic each steered to the path that serves it best, with security policy applied in the same device.
- Application-aware steering and per-path SLAs
- Health measured to Microsoft 365, Google DNS and Teraco pollers
- Sub-second failover and session continuity for voice
- Firewall, IPS and SSL inspection in the same edge, no extra box
Underlay media
The right medium for each site
Fibre
Dedicated and broadband fibre from every major South African network, with diverse routes where uptime matters. Layer 2 on-ramps into Teraco and the cloud providers.
Microwave
Licensed and unlicensed point-to-point and point-to-multipoint links for sites fibre can't reach, as primary access or as true physical diversity to it.
Mobile
Fixed LTE and 5G with business APNs, as primary access for small sites and as failover for every site, with SIM and router lifecycle managed.
Satellite
Geostationary and LEO services for remote operations, mines and farms, where nothing else reaches.
Services
From the link to the whole WAN
WAN design & migration
Site surveys, capacity planning, routing and segmentation, and the migration plan from MPLS or legacy VPNs to SD-WAN, run as a project with a cutover plan and a rollback.
Managed links
One contract and one service desk for every circuit, every carrier, with monitoring and carrier escalation handled by us.
Load-shedding resilience
Power-aware designs: LTE failover, battery-backed edge equipment and alerting, so an outage at the substation doesn't become an outage for the business.
Reporting
Per-site and per-application performance reporting, SLA compliance against the targets we agreed, and capacity trends ahead of the renewal conversation.
